[Pkg-xen-devel] Bug#674088: xcp-xapi: vbd-plug to dom0 does not creates /dev/xvd* devices in dom0

Package: xcp-xapi
Version: 1.3.2-6
Severity: normal
Tags: upstream

Normally (in 'iso-based' XCP) is possible to attach VDI to dom0.

That operation usually looks like:

xe vbd-create vdi-uuid=... vm-uuid=(dom0 uuid) device=N
xe vbd-plug

I done those steps in xcp-xapi and got success (no error), but no xvd* device found.

Here operations log:

# xe vbd-create vdi-uuid=c95af56f-799f-49ad-a64f-82eca3299b50 vm-uuid=d859ed1a-760f-9928-b5be-f0ab1790b15f type=Disk mode=RW device=2
b2e8f7b3-34c4-fe9a-486e-6551b8ba4165
# xe vbd-plug uuid=b2e8f7b3-34c4-fe9a-486e-6551b8ba4165 
# ls /dev/xv*
ls: cannot access /dev/xv*: No such file or directory
